Answer:
75%
Step-by-step explanation:
One way to find this out is to divide 15 by 20
15/20 can be simplified into 0.75.
Another example:
Let's say a student does absolutely horrendus on the test, and gets only 4 questions correct out of 20. You can do 4/20 which is 0.2 in decimal form. (You can use a calculator.) This means that in this example, this student got a 20% on the test.
The answer should be the first one, 2. Do you need and explanation?
4x+y/2y-x
Start by replacing all of the variables.
4(2)+4/2(4)-2
Now work multiply.
8+4/8-2
Now add.
12/6
That is your fraction. But you must simplify it.
Its simplifies to 2.
Answer:
a. <-28, -8>
Step-by-step explanation:
The given vector is
u = <-7, -2>.
To find 4u, we multiply the given vector by the scalar 4.
4u =4 <-7, -2>.
4u =<-7\times4, -2\times4>.
We multiply out to get;
4u =<-28, -8>.
The correct choice is a. <-28, -8>
The answer to your question is 1 I think
Answer:
37 m^2
Step-by-step explanation:
The shape can be broken down into a rectangle (on the top), two triangles (at the side) and another big rectangle (centre)
Area of one triangle
= 1/2*base*height
= 1/2*4*1
=2 m^2
Area of 2 triangles= 4m^2
Area of the small rectangle
= Length*breadth
= 1*3
= 3 m^2
Area of large rectangle in the same way
= 4*8
= 32m^2
Total area
= Sum of all the sub-areas
= 32+3+2
=37 meters^2
